TILLIE K. FELDMAN', or New ELECTRICAL WATER-HEATER.

T a all 'who'n 'l. it 'm (13 concern Be it known that I, Josnri C. FELDMkN, a citizen of the United States, and a resident of the city of NewYork, borough of Manhattan, in the county and State of New York, haveinvented a new and Improved Electrical ater-Heater, of which thefoLlowing is a full, clear, and exact description.

. This invention relates to automatic electric heaters, and among theobJects of the present improvement is to provide a structure ofrelatively small dimensions whereby it is easily transported in onesgrip or suit case for easy attachment to any convenient 5 electric plugor socket.

Another object of the invention is to provide a small compact automaticheater for water or other liquids having foldable legs soarranged as toprovidea broad basei practice, but which will occupy a relatively smallamount of space when being packed or carried.

A further object of the invention is to provide an improved switchdevice whereby the heating current will be completed automatically withthe simple movement of the delivery valve to open position for hotfluid, but which is inoperative-or inactive when the same valve isturned in the opposite direction to deliver cold fluid.

Another object of the invention is to provide an automatic-switch soconstructed and arranged that when the faucet is turncd'toward'closed orneutral position far enough to break the circuit the circuit cannotagain be closed to heat the coils unless the faucet is first turned tosubstantially complete neutral or mid ositioIi.

Another 0 ject of the invention is to prevent the stopping of the flowof water with the switch closed.

With the foregoing and other objects view' the invention consists in thearrangement and combination .of parts. hegeinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggestcdherein, still for the purpose ofillustrating, a practical embodiment thereof reference is had to theaccompanying drawings, in which like reference characters designate thesame parts in the several views, and in which Figure 1 is a verticalsectional view of my present improvement, the faucet being shownadjusted to deliver hot water. i

Referring now more specifically to the drawings, 1' show an automaticwater heater, and by the term water as employed hereinafter I wish to beunderstood as covering 1 broadly any liquid or fluid to be deliveredthrough or from. the faucet, comprising a base 10 of any suitablematerial having an inlet port 11 with which is associated a couplingnipple 12 for connection with any source of supply of water, such forexample a standard -\\'ater faucet, reservoir, or as indicated in Fig. 1a jar 13 from which a tube 1-l conveys the water to the'nipplc. The baseis bored transversely forming aseat 15 v for the plug lfi constitutingthe rotatable member of the faucet. Ahandle 17connccted to the plugserves to manipulate the same and indicate its position. 18 indicates adelivery nozzle held from movement upon the outer end of the plug asbymeans of a bracket 19 fixed to the front of the base. The upper portionof the base is bored at 20 and 21, these bores being vertical and havinglower ends merging into the seat 15. The upper end of each bore 20 01-21is also counterbored as at 22.

The base is provided with pairs of downwardly projecting lugs 23 betweeneach pair of which is pivoted at 24. a fle'g 25 of any suitable design.These legs are preferably three in number so as to insure steadiness ofsupport,"and two of them are arranged at .the front on opposite sides ofthe faucet and having a wide hearing insure maximum stability for-theheater in the manipulation of the faucet plug, it being borne in mindthat the entlre device is relatively small and tilt or upset. The meansfor connecting the legs to the. base, however, provides for easy nestingof the legs sihce they are adapted to swing toward one another or thevertical axis of the heater, and they occupy no more width of space thanthe main portion of the heater.

i The faucet plug 16 is bored cei-itrally from' each end as shown atlfi'and 27 leaving, however, a wall 28 separating these two bores.

- In one positionof theplug as shown in Fig.

1 the bores 11 and are brought into con 1 munication through lateralports 29 and 30 both of which communicate with the axial bore 26. Atthis time'the delivery bore 27 is in communication with the bore 21through :1 port 31., 32 indicates a by-pass communieating with the innerend ofthe bore 27 and extending rearward over the wall 28 as far thevertical axis ofth'e bore 11 with which it communicates when the plug isturned through 180 degrees from the position of Fig.

1. Thus the inlet bore 11 is brought into direct communication throughthe by-passB'zZ with the deli\'er \"bore 27. Those portions of the plugat this time adjacent to the bores 20' limit the extent of rotation ofthe plug in 'either direction from the normal position in which thehandle 17 is upright. The plug is held in the tapered seat 1:) by a nut33 on the outside of which is a lock nut 34 having a flange. 35extending inward over the nut 33. The periphery of the lock nut- 34 isprovided with a series" of teeth 36 as shown in Figs. 4:, 5, and 6. i

Above the base is a core 37 made of porce- 4 lain or its equivalent andprovided with a.

nmltiplicity of vertical holes extending entirel y through the same. Twoof these holes 38 and 39 communicate respectively with the base bores 20and 21.' The lower end of the core is provided with a p'air of bosses 40surrounding the lower ends of the holes 38 and 39 and which project intothe counterbores 22 of the. base and so positively hold the core fromrotation, when the shell 41 surrounding .the core is being screwed intothe internally threaded rim 42 at the top of the base. Any suitablepacking or gasket means is fitted between the core and the top of thebase to prevent leakage. Except for the bosses 40 both upper and lowerends of theyoreare flat and smooth. Between the holes 33 and 39 are an'iultiplicity of holes 43 through a l of which 49. one located in eachof the holes 43. One

through all of -the remaining holes 43 through alternately located upperand'low er hy-passes 4t and -15.

In addition to the holes 38, 39, and 43 the core is provided withsockets 46 into which are fitted a pairof binding posts l7 and 48.

i The water passing through the core from the hole to the hole39isahnost instant'ancou'sly heated by a resistance device within the coreand comprising. a'series of coils end of the resistance device is fixedat 50 in the binding post 47 and extends thence to the nearest coil 49along a by-pass similar to the by-passes- H. Thence the direction of thecoil orywire conneetingeach coil with the next follows the same courseas the flowof water through the consecutive'holes and by- 1 passes 45,the resistance wire finally, however, leading from the last coil 49 tothe binding post 48 at the point 51.

. The binding posts project upward from; the coreinto anysuitable cap orfdome 52 securedin or'to the shell 41. A pair of conductors SS-and 54are connected respectively to the-upper ends of the binding posts 47 and48 within the dome and lead outward therefrom through outlets. 55 fittedin slots 56 formed in the rear wall of the'dome. The lower edge of thedome as indicated in Fig.

1 may serve to hold-the locking ring 57 in place, which serves to sealthe upper end of the core by means of a gasket 58 fittedagainst l thesmooth top thereof. The top of the domeis provided with a neck 59 whichmay serve as a. holder or support for any device such as the jar 13. i IUnder normal conditions when no water isto be delivered or when coldwater is to be delivered it is obviously undesirable to permit a currentto pass through the resistance member. and hence I- provide means toautomaticall y control the current simultaneously with the control ofthe hot Water delivery. 60 indicates a switch easing shown as located atthe rear of the heater and within which i the lock nut or mutilated gearis located at the rear ofthe faucet plug. The main conductor is locatedat 61 leading into oneside of the casing 60. This feature-may beregarded as an ordinary double wireeleetrie cord of any suitablelengthand adapted to be attached in any well known or conventional manner withanycon'v'enient' electric socket.

' One wire'62 is connected within the casing to a tumbler 63 anddirectly or-electrically to a knife blade-64' i 'ai'ried the tumbler.The

knife blade is adapted to engage with the a fixed lu 87 carried b y thebracket 82, this two blades constituting thereby a wi position eingmaintained by a spring 88 {'kiownitype' of knife blade switch.
